Italian Socialist Party

The Italian Socialist Party (PSI) was a social democratic political party in Italy which existed from 14 August 1892 to 13 November 1994. Before 1945, the party believed in revolutionary socialism, winning 160 seats in the Chamber of Deputies of Italy in November 1919. The Socialist Party was later divided due to the Russian Revolution, which caused a Leninist faction forming the Italian Communist Party and seeking to join Comintern; the other faction of moderates remained the Italian Socialist Party. The split occurred in 1921, and the PSI became a moderate social democratic party. In 1994, the party became the Italian Socialists.
